In the event that the RMI device is unreachable, the calls to rmi_set_mode() or rmi_set_page() will fail before registering the RMI transport device. When the device is removed, rmi_remove() will call rmi_unregister_transport_device() which will attempt to access the rmi_dev pointer which was not set. This patch adds a check of the RMI_STARTED bit before calling rmi_unregister_transport_device(). The RMI_STARTED bit is only set after rmi_register_transport_device() completes successfully. The kernel oops was reported in this message: https://www.spinics.net/lists/linux-input/msg58433.html [jkosina@suse.cz: reworded changelog as agreed with Andrew] Signed-off-by: Andrew Duggan <aduggan@synaptics.com> Reported-by: Federico Cerutti <federico@ceres-c.it> Signed-off-by: Jiri Kosina <jkosina@suse.cz> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
